The main chord riff....ie the intro...is sus2 chords:
                Bsus2                                                           Dsus2
E|---2------------5-------------|
B|--2-2-2-2------5-5-5-5--------|
G|--4-------4----7-------7------|
D|--4------------7--------------|
A|--2------------5--------------|
E|--x-------------x-------------|

Hold the chord while you play the little line on the 2nd & 3rd string. So in the verse, when I say "Bsus2" 
mean the riff above.

E|-----| A>>>B---  means bend note A to the pitch of B.

an' I                   received this gift from you

A                                                               E                                                                                                       D                                                                                                       E
Pleasantly surprised, I never thought you'd realise that maybe

Bsus2           Dsus2
I                                               have taken this from you

A                                                       E                                                                                                       D                                               E
If I was deserving, who am I to disagree

A                                                                       E                                                                                       D                                                               B
How can I refuse this, even if I don't deserve it?



And now, I give this gift to you
Could have got you anything but this will have to do
It's how I give this gift to you
Doesn't seem like much but it's the best that I could do
I'm giving everything away before I go for good.



F#5                                                                                                             E
And once you give the gift away
                                                D                                                                                               Bsus2
there's nothing you can do about it.
F#m                                                                             E
Nothing that you do or say
                                D                                                                                               Bsus2
can change the way I feel about it
F#m                                                             E
Try to look inside of me
                        D                                                                                                       Bsus2
To find the gift that I am giving
F#m                                                                     E
Glad you had a chance to see
                                D                                                                               Bsus2
the gift that I'm delivering
